Groovy-Eclipse Feature	2.9.2.xx-201708160036-e47	org.codehaus.groovy.eclipse.feature.feature.group	Codehaus.org

I am writing a script with project references to our companys business objects. When doing code changes or switching tab, Eclipse is freezing for many seconds.

This behavior applies also to MyEclipse 2016 CI.

I don't know if this errors from log have anything to do with this issue:
